Juventus shares soared more than 20 per cent on Wednesday after Cristiano Ronaldo scored a hat-trick to send them into the Champions League quarter-finals.
Their 3-2 aggregate victory over Atletico Madrid on Tuesday night means Juve will receive around £9.3million in additional payments for making it through.
That cash is on top of the £8.2m the Italian giants made for reaching the last 16 of the competition.
At 9.40am on Wednesday morning, shares in the club were up 16 per cent after hitting their highest since late January in early trading.
The shares were also on track for their best day since October, 2013.
‘Considering the amount they gain by qualifying for the next round against the odds, it is quite fair,’ said a trader.
Juventus are controlled by Exor, the investment holding of Italy’s Agnelli family, which owns nearly 64 per cent of the club.
